Taran is also referred to as Saint Taran, Taran Svami and most endearingly Taaran Taran, perhaps after the fashion of his inspirer Acharya Kundakunda. Taran Panth, the (sub-)sect of Jainism which he founded, is the community into which Osho is born. Taran was born in the 15th century in the upper Narmada area of Madhya Pradesh (which includes Jabalpur, Sagar and Gadarwara) and this area has remained one of the principal centers of his people.
Sarva Dharma Sammelan, or All Religions Conference, is a regular exercise in inter-faith harmony held in several Indian cities, organized mainly by the local Jain communities. In Jabalpur, it is has been held every year since 1939, with Osho participating from 1951 to 1968. "Interfaith harmony" is a somewhat inadequate phrase meant to stand in for the principle held deeply and widely in all of Jainism that all viewpoints are partial and limited, including those in Jainism, and thus that hearing the viewpoints of many others can promote understanding and peace.
Many of Osho's books are on Jain themes. It is a natural starting-place, and as a religion with such useful principles as the one above and its openness and relative lack of rigid dogma, its themes resonate easily with Osho's themes. And conversely, Jains as a community have been interested in Osho since he began participating at their conferences and possibly before. And their interest has not been dimmed by his speaking against Mahavir, nor even by the notorious incident where he surprised his sponsors, among them prominent Jain dignitaries, by speaking about sex -- see Talk:Sambhog Se Samadhi Ki Or (संभोग से समाधि की ओर) -- and they walked off the stage where they had been sitting, expecting to hear a talk on love. They cancelled the rest of the scheduled talks but did not cancel their interest in him. -- doofus-9 (talk) 12:09, 12 October 2014 (PDT)
Laherubhai's memoir Blessed Moments with Osho contains many references to and stories about Osho's appeal to the Jain community. For example, he reports that the three Mahaveer Vani series of eighteen talks each given in the annual Jain Paryushan observances packed Patkar Hall in Mumbai to overflowing, with many Jains arriving early to make sure they got seats. -- doofus-9 22:54, 24 August 2019 (UTC)
On the question when was last Osho's visit on Taaran Jayanti Shailendra shared images (on the right) on Taaran Jayanti: 1964-1969. Image with 1968 is missing here.--DhyanAntar 10:09, 23 November 2020 (UTC)
Since 1939 there were Saint Taaran Taran Birth Anniversary Celebration, later they were renamed to Sarva Dharma Sammelan, somewhen in late 60s. Sources: early Osho's letter, most late found is Letter written on 19 Nov 1963 am, and Neeten.
Although i became confused if it so: other Letter written on 6 Oct 1961 mentions earlier talk on ‘sarv-dharm-sammelan’... Who can share light on it?
I added events on Taaran Taran Jayanti for 1959-1969 in Timeline. Its celebrations for 50s i skipped as there are unceartainties for me: some events should be, some - not according to Osho Source book. I left it someone else to sort out.--DhyanAntar 04:19, 24 November 2020 (UTC)
